TRICK-PICTURE.

concern: Be it known that I, HENRYG. Pnrs'rnrno, a citizen of'the United States, and residing at Covington, Kenton county, State of Kentucky, have invented certain new and useful Im rovements in Trick-Pictures; and I do declare the following to be a clear, full, and exact descri tion of the invention, attention being calls to the accompanying drawing,

with the reference characters marked time on, which form also a part of this speclfication.

This invention relates to devices which are in form of puzzle-pictures, or trick-cards and in which by appropriate manipulation the a pearance of certain ictorially repreed objects is suddenly c anged.

The objects of my invention are to produce such cards in a manner that they may be cheaply manufactured, and to have them of a sha e and form which permits them to be readi sent through the mailslike picture car s.

also illustrated in the In the following specification and particularly ointed out in the claim at the end thereof will be found a full descrlptlon of my invention, also of its manipulation, parts and manner of manufacture, which latter is accompanying drawing, in which' Figure 1, shows afront-vlew of such a picture-card in normal condition. Fig. 2, is

a horizontal section of the same, taken between its longitudinal edges and immediately below the upper oneof these edges. Fig. 3, in a view similar to Fig. 1, shows the appearance of the card changed. Fig. 4, in a section similar 'to Fig. 2, Illustrates manipulation required to bring about the changed appearance shown in Fig. 3. Fig. 5, shows the card from the rear in perspective view and in normal condition. Fig. 6, shows the part which forms the front of the device.

Fig. 7 shows the intermediate or movable part of'it and which in the complete device 1s immediately back of the front.. Fig. 8, shows that part which forms the back of the device.

.The front A of the device is made of a sheet .of trans arent material like transparent paper, cel uloid, or gelatin for instance. Glass while an equivalent is less suitable on account of its fragility and weight. The back B is made of suitable material of limited. thickness and weight, like plz ilper, pasteboard, or card-board preferably. ese

v Specification of Lctters latent. P t t d July 2 1910, Q Application filed July 29, 1908. Serial No. 445,851.

two parts are secured to each other at their edges in any suitable manner as for instance by binding-strips O which may be of paper or fabric, lued over these edges so as to overlap bot front and back as shown. In securing these two arts to each other, due regard 1s glven to t e presence of an intermedlate member D, preferably of aper, or cord-board, which is loosely placed between said two parts before their connection to each other is completed, said parts being sufliparts being shown as sllghtly spaced from each other to prevent confusion. In reality however they lie closely against each other, so that the resulting device is only of limlted thickness to permit of its ready insertio r 1,into an envelo for instance. A flap E is provided on t e rear-side of slidin member D Whereb it is manipulated, sai flap being accessiblie made for the purpose in back 13.,

The flap may be obtained in any suitable way, 1t may be a part of member D, which for such purpose is cut accordingly, the separated parts of the paper being bent up, or a plece of paper ma be asted on for the purpose as shown. n eit or case this fla 1s yleldmgly connected, to permit it to lie down flat as shown in Fig. 2, to revent it from interfering with insertion o the card into an envelop, and for other obvious reasons. It may however be entirely omitted in which case the slide is manipulated b the end of a finger placed against it through opening 6.

The subject matter of the picture, whatever it may be, is divided in two complementary parts, one part of it being applied to the transparent front A, and the other to the front side of slide D. The application in both cases is preferablyby painting, or by printing, and as to the front the arrangement of the picture and use of colors is such as to render the front opaque with the exception of that ortion of the picture which is supplied, or led in by the complementary portion of the picture which is placed on the slide, said portion on the front eing left blank and transparent.

To provide for a quick change of certain through an opening 6,

there are parts of this composite picture,

ortions d two su' h complementary pictureand d on the slide arranged s1 e side, and of corresponding outline an each fitted to fill-in thetransparent space a of the front. The movement of the slide is limited by the closed ends of the device, and its length is reduced so that it may be moved latera y in either direction, the complementar picture-portions on it being so located t at either one or the other of them is behind the trans arent portion a of the front'in either 0 the extreme positions of the slide. Thus a complete picture is always presented by the front by means of these two com lementary pictureortions d d on the sli e, either one of whic shows through the transparent portion a.

All other parts of the slide are hidden by the opaque portion of the front, rendered so by the plctureortion thereon, so that nothlng occurs or s ows which might interfere with a lperfect representation of the particular su 'ect matter.

The slide is old to move in proper direction by being closely fitted between two of the closed, opposite edges of the device, or by flap E which may? be closely fitted to opening 6. (Observe ig. 5.)

The particular subject of the picture ghown in the drawing 1s a dog-house and a In the condition in which the picture is shown in Fig. 1, the do is not vis1 1e, while in Fi 3, it appears in the door-o ening. This 0 ange is o tained as follows: A lparts of the front are rendered opaque by the application of the means which produce t e picture thereon, with exception of the por- 1 tion indicated at a which 18 left blank and transparent see Fig. 6. On the slide D there are two icture-portions, either one of which is comp ementary to this transparent portion in the front and adapted to re ister therewith. Portion 01 represents simp ythe door-openin and adjacent parts of the front-wall 0 now shown behind the transparent frontportion in Fig. 1.-

When the slide is shifted by manipulation of flap E as shown in Fig. 5, portion d moves away from behind the transparent front portion, and portion d, on the slide the house. The portion is moves into position, whereupon the do appears in the door-opening as shown in ig. 3.

The problem illustrated is a very simple one, but the device is susce tible of many changes by a wide range 0 available subjects of any character serious and comical.

New designs and subjects may be readily provided for in unlimited varieties and at imlted expense, since the pictorial matter may be producedby printin Nor is a picture limited to one movabl or changeable object as here shown. Instead there may be several transparent portions or spots on front A, and for each of which com ilementar portions are provided on the sli e.

t is to be noticed that no part of the slide is visible at any time since in its movements it is always entirely confined and inclosed within the edges of the card and fully covered by the intact and immovable front so that if the manipulation on the back is c everly performed, it is not readily apparent to a beholder how the change is effected.

Having described my invention, I claim as new: 7

A flat trick-card consisting of an intact, immovable front of trans arent material, part of which is rendere opaque by aplication thereto of a picture, the other art eing leftblank and transparent, a barn: of thesame size which has an opening within its edges, means whereby front and back are secured to each other around their edges and in a manner to close the space between front and back all around the edges of the card a slide .of non-trans arent material fitted between the front an back and having for the blank transparent art of the front, two picture-portions, eac of which is adapted to register with the blank part of the trans arent front, and a foldable flap of the slide and within the on the bac edges of the openingin the back through which it becomes accessible and whereby t e slide ma be manipulated by moving said flap bac and forth within said opening from one end thereof to the other.

In testimon whereof, I hereunto aflix my signature in t e resence of two witnesses.
